autogen.sh (a.k.a. buildconf) provides automatic build system preparation and is generally very useful to projects that use the GNU build system (i.e. the GNU autotools: autoconf, automake, and libtool). It is a POSIX shell script that is used for preparing a build system for compilation, verifying versions, ensuring necessary functionality, and overcoming many common build preparation issues.
WebJob downloads a program over HTTP/HTTPS and executes it in one unified operation. The output, if any, may be directed to stdout/stderr or a WebJob server. WebJob may be useful in incident response and intrusion analysis as it provides a mechanism to run known good diagnostic programs on a potentially compromised system. WebJob also provides a framework that is conducive to centralized management. Therefore, it can support and help automate a large number of common administrative tasks and host-based monitoring scenarios.
Sfront compiles MPEG 4 Structured Audio (MP4-SA) programs into efficient C programs that generate audio when executed. MP4-SA is a standard for normative algorithmic sound, which combines an audio signal processing language (SAOL) with score languages (MIDI and SASL). Under Mac OS X and Linux, sfront supports real-time, low-latency audio input/output and MIDI input. Under Mac OS X, sfront supports the creation of AudioUnit plug-ins. The documentation includes a book about SAOL programming.
TAO (The ACE ORB) is an advanced, CORBA-compliant, real-time Object Request Broker (ORB). It is designed to meet the stringent Quality of Service (QoS) requirements of real-time applications, resulting in superior end-to-end predictability, efficiency, and scalable performance. It implements the latest CORBA specifications from the OMG. It is built with components from the ADAPTIVE Communication Environment (ACE) C++ framework, resulting in a highly extensible architecture, adaptability to a wide variety of situations, and portability across a broad range of platforms. Although TAO was designed to meet the demanding requirements of real-time applications, it is also well-suited for general-purpose CORBA applications.
Agar is a toolkit for graphical applications. It features a modern GUI system with an unobtrusive API. Agar can use different graphics interfaces, such as SDL and OpenGL, and it has been ported to numerous platforms, including game consoles and embedded systems. Agar is implemented in C, but can be used from other languages.
Factor is a dynamically-typed stack-based programming language. Factor runs on various OSes and CPU architectures, and provides an optimizing compiler, interactive development environment, powerful collections, higher order programming, continuations, and a growing library of contributed code.
